| abstract |
Condoms are disclosed of the type having a main sheath portion closed at a distal end and open at a proximal end thereof, which are amenable to construction from thermoplastic elastomeric materials. In one preferred aspect, such condoms have an annular-shaped sealing element, formed of an elastic material, circumscribing an interior opening of smaller size than the proximal end opening of the condom, and joined at the outer periphery of the sealing element to the main sheath, at or in the vicinity of the proximal end opening. Such construction thereby provides a membrane dam in the proximal segment of the condom to enhance its effectiveness as a contraceptive and to minimize the incidence of sexually transmitted diseases. Also disclosed are various condom manufacturing and processing apparatuses, as well as applicators for applying the condoms to the penis of a wearer. |
